Application filed December 3, 1909. Serial No, 531,183.

To all whom it may concern: i

Be it known that I, FRANK VSETECKA,

' citizen of the United States,. residing at /Vaucoma, in the county ofFayette and 5 State of Iowa, havevinvented certain new 'and usefulImprovements in Automobile- Horns, of which the following is aspecification. I r This invention relatesto pneumatic-signals and moreparticularly to a horn'especially adapted for use on automobiles and thelike.

- The object of the invention is to provide a comparatively simple andthoroughly eflicient device of the character described, designed to takethe place of the ordinary rubber bulb and so constructed that the samemay be readily taken apart to effect any necessary repairs thereto.

A further object is;.-t0 provide a horn in which the vibratiniieed' is;actuated to sound an alarm by sliding the bulb or cap longitudinally onthe air conductor.

A further object is to rovide an .au't0 mobile horn including a slidingcap or bulb having'a cylinder disposed within the same for thereception'of a stationary plunger, there being a coil spring interposedbetween the plunger and cap for returning the latter to normalpositionafter said .capis depressed. I

A still further object of the invention is generally to improve thisclass of devices, so as to increase their utility, durability andefiiciency, as well as to reduce thec'ost of manufacture. I

Further objects and advantages will appear in the following description,it being understood that. various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims. I

For a full understanding of the invenl l0I1 and the merits; thereof andalso to acquire a knowledge; of the 'details ,of construction and themeans for effecting the result, reference is to'be had to the'follow-.ing description and accompanying drawings, in which:

' Figure 1 is a side elevation of aportion of an automobile rovided witha horn constructed inaccor ance with my invention; Fig. 2 is a verticalsectional view of the alarm; Fig; 4 is a transverse sectional view-taken on the line 44 of Fig. 2 and looking in the direction of thearrow.

Corresponding and like parts are referred to in ,the followingdescription andindicated in all the views of the drawings by the samereferencecharacters.

The device comprises a tubular member or air conductor 5 having itsupper end threaded at 6 and its lower end 'operativ'ely connected with acoupling 7 carrying a vibrating reed or other sound producingelement,.indicated at 8. 4

Slidably mounted on the air conductor 5 is a bulbous cap-pieceor'actuating member preferably formedof metal and constructed in twosections 9 and 10; The upper section 9 is substantially sphericalincontour and is provided atitslower end with interior threads 11 forengagement with the correspondingly-threaded end of the lower section-10, there being an annular shoulder 12- formed on said lower section forengagement with the adjacent end of theupper' section 9, as shown. "Thelower section 10 is preferably inclined or tapered in the di-- rectionof the. air conductorf 5 and is provided'with a centrally disposedopening 13 85 thus to allow the cap'to slide freely on the to permit thepassage of said conductor,

conductor when it'is' desired -to actuate the med 8 to sound an alarm.Disposed within the upper sectiont), is a cylinder 14, the

lower endof which extends within the s'ection 10 and is welded orotherwise rigidly secured thereto, the lower or fixed end of thecylinder 14 being provided with an in wardly extending stop flange 15for engagement with the p unger 16. The plunger 16 comprises spaceddisks or plates 17 having a strip of leather, rubber or other yieldablematerial interposed between the same and retained in position by meansof clamping; nuts 18 bearing against the disks l7, and engaging thethreaded end 6 of the conductor 5, as best shown in Fig. 2 of thedrawings.

.A coil spring 19 interposed between the H plunger 16 and theupper endof the cap section 9 for the purpose of returning the cap to normalposition after the same. has been depressed to actuate-thesoundingelementS; In order to permit the escape of air from horn bulbshowing the cap piece in noromal position;'Fig. 3 is a similar view ofthe bulb or cap piece depressed to sound an the chamber 20 when the capis released, the walls of the opening 13' are formed with a plurality ofspaced grooves or recesses 21 through which the air is forced when theconductor '24 with said coupling member 7,

cap is moved to extended position by the action of the coil spring 19.

The upper section 90f the cap is prefer- I ably covered with a strip ofleather, rubber 'or other yieldable material 22 so as to permit theoperator to readily grasp the cap when operating the device.

Thus it will be seen that when a downward pressure is exerted on thecapfithe latter will slide longitudinally on thei'air bond'uctor 5'andthe airin the upper section 9-will be forced through said air conductor'5 and against the reed 8 so as to'vibrat'e' the same and soundan-alarm, the 'spring'.19 serving to return the cap to extended ornormal position after the hand has-been released from said cap.-

Thehorn proper, indicated at 23 may be connected directly with thecoupling member 7 or through the medium of a flexible 1 as shown in Fig.1 of the drawlngs.

' -It will herebe noted that the-,construction B-y removing the uppersection 9 and detaching the coupling member 7, the lower section 10 ofthe bulb carrying the cylinder '14, may be removed from the airconductor 5 so as to expose the plunger 16 and its associated parts whenit is desired to effect any repairs thereto.

" of the-device is such that the cap will work equally as-w'ell in coldweatheras in warm- I weather, which is a very important feature "inthisclass of signals. p I I Having thus described the invention, whatvis claimed as-new is:

" '1. .An automobile horn including an air 1 conductor, a soundproducing element disried by said conductor,
